Chapter 1

Adam, Seth, Enosh (1 Chronicles 1:1)
According to Genesis 4:1-2 and 4:25, Adam and Eve had three sons who were named, in addition to a large number of additional sons and daughters who were not named (Genesis 5:4). Only Seth is mentioned in this verse; neither Cain nor Abel are mentioned at all in this passage. This suggests that God moved the Chronicler, who was responsible for compiling this selected genealogy, to do so for a particular reason.

Noah, Shem, Ham, and Japheth. (1 Chronicles 1:4)
This father and his three sons – each survivors of the flood – became the basis for the nations in the post-flood world.

All these were the children of Keturah: (1 Chronicles 1:33)
This was the second wife of Abraham, taken after the death of Sarah (Genesis 25:1-4).
